將數組轉換爲帶有鍵和值的對象javascript

Question

如何將數組元素隱藏或添加到對象中。

現在

arr = [ 
    ["1/1/2017",113], 
    ["3/11/2017",58], 
    ["3/12/2017",70], 
    ["3/13/2017",76] 
] 

應該

arr = [ 
    {date:"1/1/2017", count:113}, 
    {date:"3/11/2017", count:58}, 
    {date:"3/12/2017", count:70}, 
    {date:"3/13/2017", count:76} 
] 

Answer 1

arr.map(function(arr1) { 
return { 
    date : arr1[0], 
    count : arr1[1] 
} 
})
